Verbally reported perceived amplitude of rotation vs. current for 2 s trains of single canal electrical stimulation at different stimulus rates on the 1st test day in all subjects. A, B, D, E: perceived yaw rotation amplitude leftward vs. current for right lateral canal stimulation in subjects S1, S2, S3, and S4. C: perceived pitch rotation amplitude backward vs. current for posterior canal stimulation in subject S2. Inset: perceived yaw rotation and cumulative eye movement amplitude vs. current for 2 s trains of electrical stimulation at 300 pps for 3 subjects.
